| General description【一般描述】 | Benzoic acid melting point standard, 121-123 ℃ is useful as a melting point calibration standard while defining the purity of pharmaceutical chemicals. Its melting point value is determined with an average of 6 to 12 measurements using a Büchi B-545 instrument that is calibrated against primary standards. |
| Application【应用】 | Melting point standard 121-123 ℃, benzoic acid is an analytical standard used to calibrate melting point instruments, in the thermodynamic mode of operation. It is also used in R & D labs for chemical quality control (QC) and quality assurance (QA) to identify solid crystalline substances and to check their purity. |
