DIBOC serves as a protective group for amines, for instance in solid phase peptide synthesis

RHODIAROME is a extra pure Ethyl Vanillin - Free from any other additive.

MALONIC ACID is the ionized form, as well as its esters and salts which are known as malonates. MALONIC ACID is used as a precursor in polymers and polyester. It is used in flavours as well as in the fragrance industry. It is used to control acidity and it is used in pharmaceutical products.

Pyroglutamic acid, also known as PCA, 5-oxoproline, pidolic acid, or pyroglutamate, is an uncommon amino acid derivative where the free amino group of glutamic acid or glutamine cyclizes to form a lactam. It plays a role in the glutathione cycle, being converted to glutamate by 5-oxoprolinase, and is found in many proteins, including bacteriorhodopsin. N-terminal glutamic acid and glutamine residues can spontaneously cyclize to become pyroglutamate, complicating N-terminal sequencing with Edman chemistry due to the absence of a free primary amino group. The enzyme pyroglutamate aminopeptidase can remove the pyroglutamate residue, restoring a free N-terminus. Pyroglutamic acid exists as two distinct enantiomers.
