Medicine References

Medical Reference Guide. Our comprehensive and interactive medical reference

A drug reference standard is a standardized substance which is used as a measurement base for similar substances. Where the exact active substances of a new drug are not known, a reference standard provides a calibrated level of biological effects against which new preparations of the drug can be compared. drug reference solutions and patient education materials put the best available information into the hands of clinicians and patients. They supply critical information regarding dosage, efficacy, interactivity and allergies, even suggesting alternate therapies as appropriate. Drug reference Standards are highly characterized physical specimens used in testing by pharmaceutical and related industries to help ensure the identity, strength, quality, and purity of medicines (drugs, biologics, and excipients), dietary supplements, and food ingredients. Our Reference Standard collection consists of more than 3,100 items ranging from drug substances, related impurities, residual solvents, biologics, excipients, botanicals, polymers, Near-IR and dissolution calibrators, photomicrographs, and melting point standards. As a supplier of drug and metabolite standards for over 30 years, we are continually updating our drug standard offering to keep up with the demand of new analyses performed by toxicological and forensics laboratories. Our drug standards are available in three convenient formats. All chromatographic reference standards are supplied with a certificate of analysis certifying the identification and purity of the compound.
