| General description: | Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Ammonium chloride is formed as a by-product during soda manufacturing by Solvay process. It can be synthesized by reacting HCl with aqueous ammonia solutions. Crystals of ammonium chloride (NH4Cl) belong to the cubic crystal system. |
| Other Notes: | This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis. |
