General description

Benzoic acid melting point standard, 121-123 °C 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

Melting point standard 121-123 °C, 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.

Features and Benefits

  • Melting point calibration standard traceable to primary standards (LGC, London)
  • Grade: Analytical Standard
  • Uncertainty of measurement up to ± 0.3 °C
  • 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
