Product Character — Practical Notes

What this structure means in practice

When requesting a sample, test two things: whether it discolours or cakes after extended storage (the oxidation issue with ring systems), and how it behaves once diluted to your actual working concentration — some materials dissolve well neat but precipitate on dilution. Half a day at trial stage is far cheaper than a batch rejection.

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 aromatic organic carrying 4 oxygen, 4 nitrogen, and is strongly lipophilic, essentially insoluble in water. Comparing these against your incumbent product gives a good first read on switching difficulty.

How it behaves in a formulation

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 320~500 g/mol the material is larger and exists as colloid or polymer segments in water, working through thickening, dispersion and film formation. Ask about shear stability: if your process includes high shear, faster-than-expected viscosity loss affects the finished product.

Strongly lipophilic and essentially insoluble in water, it functions as the oil-phase component: a solvent, a thickener base or a film former. To use it in an aqueous system, dissolve it in a little solvent first or go through an emulsification step; adding it directly will not work.

Storage and handling

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: control dust and wear eye protection, as the material can irritate mucous membranes; pre-disperse high-molecular-weight material, as adding it dry into a viscous medium clumps; pre-dissolve lipophilic material in a compatible solvent before introducing it to the aqueous phase; 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.

Purchase Profile

What this product is

8-amino-5-[(2-methoxy-4-nitrophenyl)azo]-2-naphthol is a colorant or pigment compound with CAS registry number 85030-46-2 and molecular formula C17H14N4O4 (molecular weight 338.32), belonging to the dyes and pigments segment of chemical raw materials.

This entry sits in our dyes and pigments 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.

8-amino-5-[(2-methoxy-4-nitrophenyl)azo]-2-naphthol is typically applied in Dyes &amp, Pigments.

Jinan Shenghe Chemical Co., Ltd. supplies 8-amino-5-[(2-methoxy-4-nitrophenyl)azo]-2-naphthol with stable inventory and provides a Certificate of Analysis (COA) with each batch; custom repacking is available per process requirement.

Identification

CAS number: 85030-46-2 — searchable in PubChem for physicochemical, safety and regulatory data.

Its molecular formula C17H14N4O4 comprises 17 C, 14 H, 4 N, 4 O atoms.

Also known as: 8-amino-5-[(2-methoxy-4-nitrophenyl)azo]-2-naphthol · 8-氨基-5-[(2-甲氧基-4-硝基苯基)偶氮]-2-萘酚

Category: dyes and pigments

Applications in practice

Within the dyes and pigments 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.

Recorded application terms for this entry: Dyes &amp, Pigments. These are maintained against what is actually supplied rather than a generic marketing list, so if your use is not among them, describe the end product and we will re-map the grade.

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.

Specification and acceptance

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.

Ordering and supply

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.
