Phar­ma­ceu­ti­cal Impu­ri­ty Ref­er­ence Standards

We pro­vide phar­ma­ceu­ti­cal R&D com­pa­nies with high-qual­i­ty chem­i­cal prod­ucts for the reg­is­tra­tion of new drugs and gener­ic drugs, including

Phar­ma­ceu­ti­cal Ref­er­ence Stan­dards, Phar­ma­ceu­ti­cal Impu­ri­ty Ref­er­ence Sub­stances and Fea­tured Intermediates.

Pro­fes­sion­al­ism

We have a pro­fes­sion­al team with many years of expe­ri­ence in the field of phar­ma­ceu­ti­cal research and analy­sis, which can pro­vide you with com­pre­hen­sive pre-sales advice and after-sales tech­ni­cal support.

Qual­i­ty

Con­trol qual­i­ty from the source. For unsta­ble prod­ucts, retest is always done before ship­ment to guar­an­tee qual­i­fi­ca­tions. Oily or vis­cous prod­ucts are dried with a lyophiliz­er to ensure the best properties.

Ser­vice

The prod­ucts shipped by tight­ly packed with ice bags or even full cold chain trans­porta­tion to ensure prod­uct qual­i­ty. At the same time, Wat­son also plans to set up over­seas ware­hous­es in US, Chi­na, Poland, India…
