Batches are supplied with a certificate of analysis, and the supporting spectra can be sent ahead of a purchase order so your QA team can review them. Laboratories use them to validate related-substance methods, set specification limits under ICH Q3A and Q3B, and identify unknown peaks in stability samples. For nitrosamine risk evaluation, the N-nitroso standards allow confirmatory LC-MS testing against the acceptable intake limits.

Questions
Tamsulosin impurities, answered
What Tamsulosin reference materials are available?
The catalogue currently lists 34 compounds for Tamsulosin, including 16 pharmacopoeial impurities and 1 nitrosamine. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Tamsulosin impurity standard?
A certificate of analysis travels with every lot. On request we share the characterisation set, usually 1H-NMR, mass spectrum, HPLC purity and IR, and for some materials TGA or water content. Ask for the data before ordering if your QA team needs to review it.
Can Zemixal make a Tamsulosin impurity that is not listed?
Often yes. Send the structure, name or CAS number with the quantity you need and our sourcing team checks custom synthesis options, usually from 10 mg up to gram scale, with a quoted lead time.
Do you supply Tamsulosin nitrosamine impurities?
Yes. 1 N-nitroso compound is listed for Tamsulosin. They are used for confirmatory testing and method validation in line with ICH M7 and the nitrosamine guidance from the major regulators.
