Collection: Matrix Materials (for MALDI-TOF-MS)

Matrix Materials (for MALDI-TOF-MS) — compiles small aromatic compounds with conjugated chromophore groups, such as hydroxybenzoic acid derivatives, aminoquinolines, and hydroxylated acetophenones, which function as laser energy-absorbing matrices. It also includes amine-bearing naphthalene compounds that assist in the dehydrohalogenation and ionization of samples.

These matrix materials are used in MALDI-TOF-MS analysis to help co-crystallize with the sample and absorb laser energy, thereby facilitating the desorption and ionization of target molecules, including peptides, polymers, or other small molecules. Proteomics researchers and analytical chemists select a particular matrix type depending on the characteristics of the sample being analyzed, such as its molecular weight and polarity.

Example products in this collection: TCI A0317 89-57-6 5-Aminosalicylic Acid, TCI C0002 331-39-5 Caffeic Acid, TCI A0418 580-17-6 3-Aminoquinoline, TCI C0287 321-14-2 5-Chlorosalicylic Acid, TCI A0425 2349-67-9 2-Amino-5-mercapto-1,3,4-thiadiazole, TCI C1297 5331-91-9 5-Chloro-2-mercaptobenzothiazole, TCI T1888 480-66-0 2',4',6'-Trihydroxyacetophenone Monohydrate, TCI C1768 28166-41-8 alpha-Cyano-4-hydroxycinnamic Acid.

Choose the matrix type according to its suitability for the analyte class (peptides, polymers, or small molecules), and pay attention to purity and the crystal or hydrate form, as these affect the homogeneity of sample co-crystallization. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on the page of each item.
