The Trade Reporting and Compliance Engine (TRACE) is the FINRA-developed vehicle that facilitates the mandatory reporting of over-the-counter secondary market transactions in eligible fixed income securities such as corporate bonds.
All broker-dealers who are FINRA member firms have an obligation to report transactions in corporate bonds to TRACE under an SEC-approved set of rules.
FINRA TRACE data is available on Wharton Research Data Services (WRDS).

AromaDb database is a comprehensive electronic library of aroma molecules of medicinal and aromatic plants of Indian origin, as well as foreign and include detail information about aroma plants, description, plants varieties, plants accessions, chemotypes, essential oils, oil yields and constituents, chromatograms, major and minor compounds, structural elucidation data, structural data (2D and 3D) of very small size volatile molecules (< 300 molecular weight) and medium size molecules (< 500 molecular weight), physico-chemical properties, biological pathways information and cross references. Here, aroma compounds classified by structure as esters, linear terpenes, cyclic terpenes, aromatic, amines, alcohols, aldehydes, ketones, lactones, thiols and miscellaneous compounds.
The DrugBank database is a unique bioinformatics and cheminformatics resource that combines detailed drug data with comprehensive drug target information.
The latest release of DrugBank (version 5.1.4, released 2019-07-02) contains 13,445 drug entries including 2,623 approved small molecule drugs, 1,349 approved biologics (proteins, peptides, vaccines, and allergenics), 130 nutraceuticals and over 6,335 experimental (discovery-phase) drugs. Additionally, 5,158 non-redundant protein (i.e. drug target/enzyme/transporter/carrier) sequences are linked to these drug entries. Each entry contains more than 200 data fields with half of the information being devoted to drug/chemical data and the other half devoted to drug target or protein data.
FooDB is the world’s largest and most comprehensive resource on food constituents, chemistry and biology. It provides information on both macronutrients and micronutrients, including many of the constituents that give foods their flavor, color, taste, texture and aroma. Each chemical entry in the FooDB contains more than 100 separate data fields covering detailed compositional, biochemical and physiological information (obtained from the literature). This includes data on the compound’s nomenclature, its description, information on its structure, chemical class, its physico-chemical data, its food source(s), its color, its aroma, its taste, its physiological effect, presumptive health effects (from published studies), and concentrations in various foods. Users are able to browse or search FooDB by food source, name, descriptors, function or concentrations. Depending on individual preferences users are able to view the content of FooDB from the Food Browse (listing foods by their chemical composition) or the Compound Browse (listing chemicals by their food sources).
PubChem is an open chemistry database at the National Institutes of Health (NIH). “Open” means that you can put your scientific data in PubChem and that others may use it. Since the launch in 2004, PubChem has become a key chemical information resource for scientists, students, and the general public. Each month our website and programmatic services provide data to several million users worldwide.
PubChem mostly contains small molecules, but also larger molecules such as nucleotides, carbohydrates, lipids, peptides, and chemically-modified macromolecules. We collect information on chemical structures, identifiers, chemical and physical properties, biological activities, patents, health, safety, toxicity data, and many others.
The amount of data in PubChem is ever-growing, please visit the PubChem Statistics page to find out what the latest data counts are.
