1,2-O-Isopropylidene-alpha-D-xylofuranose (CAS 20031-21-4) is listed on our Chinese catalogue site, which is maintained separately from the international site. Formula C8H14O5, molecular weight 190.19. This is a polyfunctional organic compound of 8 carbon with 5 heteroatoms, predominantly aliphatic; of low molecular weight. Specifications, packaging and shipment terms are confirmed against the batch COA before any order is released.
Organic Chemicals
Catalogue applications recorded for this grade: Organic Chemicals. On the Chinese site the application list is maintained alongside the domestic supply specification, so it reflects what is actually shipped within China rather than a global marketing summary.
If you need the product in a different pack size or purity for a domestic formulation run, that is usually arranged without a minimum-order change — mention the quantity and we will quote the domestic supply option.
Packing is per order / batch confirmation (not published), and purity is per batch COA (not published). Both are confirmed at order stage rather than fixed on the catalogue page, because packing options differ between domestic and export movements. Storage: sealed, in a cool and dry place, away from direct sunlight.
Every batch leaves with a Certificate of Analysis showing the measured values. MSDS and technical documents are available on request. Contact: info@591daili.com · +86-18553102138. Quotes are returned within one business day.

When requesting a sample, check two things: whether it causes problems alongside oxidisable components in your current formulation, and how long it stays stable sealed at ambient temperature. The saturated aliphatic backbone is itself robust; risk usually comes from other components.
If you are weighing whether to switch to this material, compare three things: structural type, which decides what reactions it can join; polarity, which decides how it dissolves; and molecular weight, which decides how much to add. This product is an aliphatic organic carrying 5 oxygen, and leans hydrophilic, dispersing readily in water. Comparing these against your incumbent product gives a good first read on switching difficulty.
On quantity: for standard grades, order two to three months of usage. Long-held chemical raw materials also show packaging degradation and label loss, and that cost eventually lands in your purchase price. For intermediates and non-standard grades, trial a small order first and move to a volume price once the batch is proven.
At 120~200 g/mol, the commonest size in fine chemicals: reactive enough to be useful and easy to handle. Most pharmaceutical intermediates, food additives and personal-care ingredients sit here. Supply is mature and several grades are usually available off the shelf, with no production wait.
Hydrophilic and easy to disperse in water, which makes it a common choice for water-based formulations. In an oil-based system its role is emulsifying rather than primary, and it is worth being clear about that when selecting.
One more point: if you need a retained sample, we can include one from the same batch with the shipment. That way, when a later batch arrives, you can compare it against your retained reference instead of relying only on the new COA, which shows more clearly how stable the product is batch to batch.
On receipt and storage: store sealed in a cool, dry place away from direct sunlight and incompatible materials; specific handling and PPE follow the MSDS issued with the batch.. We accept against the batch COA by default. If you have an internal acceptance specification — assay, moisture, particle size, colour difference — send it over and we will issue the report against your standard.
1,2-O-Isopropylidene-alpha-D-xylofuranose is a carbon-based organic compound with CAS registry number 20031-21-4 and molecular formula C8H14O5 (molecular weight 190.19), belonging to the organic chemicals segment of chemical raw materials.
This entry sits in our organic chemicals range, which we hold as a stocking category rather than as a made-to-order one. Most enquiries in this group are repeat business once a grade is approved, which is why we keep batch records on file: a later order can be quoted against the same specification and compared directly with what you received before.
Jinan Shenghe Chemical Co., Ltd. supplies 1,2-O-Isopropylidene-alpha-D-xylofuranose with stable inventory and provides a Certificate of Analysis (COA) with each batch; custom repacking is available per process requirement.
CAS number: 20031-21-4 — searchable in PubChem for physicochemical, safety and regulatory data.
Its molecular formula C8H14O5 comprises 8 C, 14 H, 5 O atoms.
Also known as: 1,2-O-Isopropylidene-alpha-D-xylofuranose

Within the organic chemicals group, buyers usually arrive with an end product in mind rather than with a compound name. The practical questions are which grade fits the process, how much lead time the quantity needs, and whether the specification can be adjusted without changing the recipe. Send us the end product and we will answer all three in one quotation.
A practical note for repeat ordering: once a batch is approved, we can quote against the same specification so that subsequent orders are directly comparable. If your process changed in the meantime, tell us — the comparison is only valid within one specification.
Purity on offer is per batch COA (not published) and packing is per order / batch confirmation (not published). Both are agreed before the order is placed rather than fixed on this page. We accept against the batch COA by default; if your QA has its own acceptance specification, send it and we will issue the report against your standard. Retained samples from the shipped batch can be included on request, which makes a later comparison against a new batch much more meaningful than reading a fresh COA on its own.
Supplier: Jinan Shenghe Chemical Co., Ltd.. Samples can be arranged before a volume order so you can qualify the material on your own equipment rather than on a certificate. Lead time depends on stock and quantity, and it is confirmed in the quotation rather than promised here. Payment can be made by bank transfer with a VAT special invoice issued; within Shandong and neighbouring provinces we can arrange fast delivery, elsewhere the goods move by road or rail at normal logistics speed.
