Frequently Asked Questions

What is tretinoin (retinoic acid)?

Tretinoin (CAS 302-79-4, C20H28O2) is all-trans retinoic acid, a carboxylic-acid derivative of vitamin A. It is supplied as an active pharmaceutical ingredient (API) and retinoid raw material for topical formulations and research. We supply it to qualified manufacturers and laboratories only.

What is the difference between tretinoin and retinol as raw materials?

They are distinct compounds: tretinoin is all-trans retinoic acid (the carboxylic-acid form of vitamin A, CAS 302-79-4), whereas retinol is the alcohol form (CAS 68-26-8). Tretinoin is handled as a pharmaceutical-grade API; specify which retinoid you require when requesting a quote.

What grade is tretinoin supplied as?

Tretinoin is supplied as an API / fine-chemical retinoid raw material and as a reference material for laboratory use. Specification and grade documentation accompany each lot. Sale is restricted to qualified pharmaceutical manufacturers and research institutions.

What is the HS code for tretinoin?

Tretinoin classifies under HS 2936.21 (vitamins A and their derivatives). Confirm the destination-country tariff line with your broker, as API imports may carry additional regulatory documentation requirements. We supply commercial documentation to support clearance.

What documentation and handling apply to bulk tretinoin?

Each lot ships with a Certificate of Analysis (CoA) and Safety Data Sheet (SDS); retinoids are light- and oxygen-sensitive, so storage and handling per the SDS are required. As an API, sale is limited to qualified buyers. Request a quote with your intended use, target volume, and documentation needs.
