Isopentyl 3-(4-methoxyphenyl)acrylate (Standard) is a reference standard for Isopentyl 3-(4-methoxyphenyl)acrylate, suitable for quantitative analysis, quality control, and biochemical experiments. Isopentyl 3-(4-methoxyphenyl)acrylate functions as an ultraviolet filter.

Benzoic acid (Standard) is a standard substance that can be used for quantitative analysis.Benzoic acid (Dracylic acid) is an aromatic alcohol and common additive found in many plants.

L-Glutamic acid (Standard) is a reference standard for research and analysis in studies involving L-Glutamic acid. L-Glutamic acid (Glutaminol) acts as an excitatory neurotransmitter, an agonist for all subtypes of glutamate receptors, and facilitates dopamine release from nerve terminals.

Glycine (Standard) is a reference standard for research and analysis in studies involving glycine. Glycine is an inhibitory neurotransmitter in the central nervous system and a co-agonist of glutamate, enhancing NMDA receptor excitability. It is found in gelatin and silk fibroin and is used as a nutrient in medical treatments.

Methyl methanesulfonate (Standard) is a reference standard for research and analysis in studies involving Methyl methanesulfonate. Methyl methanesulfonate is a DNA alkylating agent that modifies adenine (to 3-methyladenine) and guanine (to 7-methylguanine), inducing base mismatches and replication errors.
