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.

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.

特点和优势

• Melting point calibration standard traceable to primary standards (LGC, London)
• Grade: Analytical Standard
• Uncertainty of measurement up to ± 0.3 ℃
• Provided with certificates of analysis and safety data sheet
• A product of analytical standard grade that meets the QC/QA requirements of melting point analysis
